Removal Of Target Ppcps From Secondary Effluent Using Aops And Novel Adsorbents, Venkateswara Reddy Kandlakuti
Removal Of Target Ppcps From Secondary Effluent Using Aops And Novel Adsorbents, Venkateswara Reddy Kandlakuti
Electronic Thesis and Dissertation Repository
Atenolol (β-blocker), Clofibric Acid (Lipid regulators) and Diclofenac (Anti-inflammatory) are the drugs widely used and reported to have adverse effects on fish and other organisms. These drugs are found at trace levels in lakes, rivers and sewage treatment plants and conventional treatment plants are ineffective to eliminate these at those levels. A high resolution LC-MS/MS was used to quantify these drugs at low levels. Various advanced oxidation methods were used for the present research to eliminate these drugs from secondary effluent. Complete removal of PPCPs was achieved by synthesizing immobilized TiO2 on a stainless steel mesh and using a combination …
Granulation Of Biochar For Soil Amendment, Breanna H. M. Bowden-Green
Granulation Of Biochar For Soil Amendment, Breanna H. M. Bowden-Green
Electronic Thesis and Dissertation Repository
Biochar has shown potential as a soil amendment, but is a fine powder that is difficult to handle and would be blown away if applied to soils without modifications. Wet drum granulation of cornstalk biochar using binder solutions of hydroxypropyl methylcellulose was initially investigated, establishing that biochar could be granulated into a form that would be easier to handle and apply effectively to the soil. Biochars from three different feedstocks were then tested along with three binder solutions. The biochar granules were free flowing and relatively strong with a significant yield between a size range of 1 to 4 mm. …
